Description
Technical field
The invention belongs to into footwear detection field, being specifically related to a kind of for becoming the proving installation of footwear water vapor permeability and water suction vapour.
Background technology
Becoming the water suction vapour of footwear and water vapor permeability and its comfortableness and wholesomeness closely related, is the key factor affecting comfortableness, wholesomeness.The factor affecting into footwear vapor pervious and water suction vapour is a lot, footwear are become to be multiple material composition, irregular complex, have vamp material, shoe lining material, material for sole of shoe, tackifier, toe box, structural design, shoe-making process etc., the moisture absorption moisture-penetrability test of simple material for shoes truly can not reflect into this performance of footwear.
Current test has two large class methods, the first directly passes into steaming process, principle passes into gauge water steam toward footwear chamber, place under steady temperature and relative humidity atmosphere, multiple weight of the test footwear (subsidiary packoff) when taking different node standing time, analyze the difference of they and initial weight, the quality of footwear water suction vapour and vapor pervious performance can be drawn into; It two is false footworks of perspiring, and mostly domestic development principle is to make pin mould with holes with metal or special material, and experiment pin mould connecting tube inserts footwear chamber, passes into steam by pipeline, and the testing and analysis under connecing is with directly to pass into steaming process identical.Water vapour, owing to carrying, just has certain pressure, is not easy to sealing.Course of conveying is easily condensed into water droplet, very far away with human body perspire temperature difference, will certainly weaken the reasonable authenticity of test data.The amount of water vapor is difficult to control, and large can condense into water droplet, penetrates into in footwear, makes the water suction vapour value testing into footwear bigger than normal; When arranging too small, perspiration water vapour all can be delivered to the external world through one-tenth footwear, becomes the unsaturated water suction vapour value making to measure of footwear water suction vapour less than normal, therefore, easily occurs the inaccurate situation of test data.
Publication number CN202335437U patent discloses a kind of become footwear moisture absorption moisture-penetrability tester, also there is following technical matters in this technical scheme: state when test condition is worn away from human body, and state when wearing into footwear with human body is variant; In footwear chamber, the amount of water vapour is difficult to control, and too conference condenses into water droplet in footwear chamber, and the water suction vapour value causing into footwear is bigger than normal, and too little water vapor is all delivered to into outside footwear footwear chamber through one-tenth footwear, and the suction vapour quantity and the vapor pervious amount that cause into footwear are all less than normal; It is all difficult point that impermeability in the temperature of steam, pressure and course of conveying controls, and therefore operability is not strong; High-power operation causes environmental protection and energy saving reduction, operating cost increases; And only for testing water permeability and absorptive mensuration, also there is the problem of function singleness in this device.
Publication number is that the one that patent discloses of CN102525035A " becomes footwear water vapor permeable and water vapor absorption test method and equipment ", there is following technical matters in this technical scheme: test philosophy is unreasonable, when namely wearing, steam is delivered in external environment through one-tenth footwear by footwear chamber, and in this technology, steam is through becoming footwear by the absorbed on silica gel in footwear chamber by external environment.
